I passed the class with an A the whole year, but there are only some answers that you can go back and check. Logarithms are the easiest to check, but it really depends on what you're doing.

enable x be the style of $5.00 packing containers and y be the style of $3.00 packing containers. a complete of 40 5 packing containers were bought, so x + y = 40 5. the quantity of money earned from each style of container is the cost of the container prolonged by ability of the style of packing containers bought. the total quantity bought is $185, so 5x + 3y = 185. for this reason, your gadget of equations is: x + y = 40 5 5x + 3y = 185 And you are able to now sparkling up by ability of substitution. x + y = 40 5 x = 40 5 - y 5x + 3y = 185 5(40 5 - y) + 3y = 185 225 - 5y + 3y = 185 225 - 2y = 185 -2y = -40 y = 20 of the $3.00 packing containers x = 40 5 - y = 40 5 - 20 = 25 of the $5.00 packing containers

you can use the formulas for solving theproblems.sometimes you mayguess check and revise.
checking is always by substitution of the answer in the data and seeing whether there is agreement.
